Title:
Pressure-sensitive adhesives containing bonded nanoparticle network structures, their manufacturing methods and their use
Document Type and Number:
Japanese Patent JP6362621
Kind Code:
B2
Abstract:
Pressure-sensitive adhesive mass comprises at least two components which respectively form a phase, from which an interpenetrating network with at least two phases is produced by a crosslinking build-up reaction, and comprises a first phase (elastomeric phase) having at least one softening temperature of less than 23[deg] C according to differential scanning calorimetry (DSC), and a second phase having a softening temperature after the build-up reaction, of greater than 23[deg] C according to DSC. The two phases exhibits a morphology of a crosslinked nanoparticle network after the build-up reaction. Independent claims are also included for: (1) an adhesive tape comprising a layer made of the above pressure-sensitive adhesive mass applied on at least one side of a carrier or on both sides of the carrier; and (2) preparing the pressure-sensitive adhesive mass, comprising (a) preparing a homogeneous mixture of at least one elastomer, at least one reactive component, preferably reactive resin or monomer and optionally a tackifier resin, where the mass proportion of the reactive component is less than or equal to the total mass of the elastomer and the optional tackifier resin, and (b) starting the build-up reaction of the reactive resin or the monomer, where dispersed nanoparticles are formed from the reactive resin or the monomer, which connect to a network of nanoparticles within the elastomeric phase.
